Mechanical properties of resin-ceramic CAD/CAM restorative materials

Dentin bond strength of two resin-ceramic computer-aided design/computer-aided manufacturing (CAD/CAM) materials and five cements after six months storage

“…Subsequently, excess cement was removed with a microbrush. For the four adhesive resin cements (Table 3), all light-curing was performed with an LED curing unit (Demi, Kerr, Middleton, WI, USA) with a mean light power density of 1,600 mW/cm 2 (measured with the MARC PS, BlueLight Analytics, Halifax, NS, Canada). For the glass ionomer cement, cylinders were fixed in the custom-made loading device for 5 min to allow self-curing (Table 3).…”

“…Lava Ultimate, also named "nanoparticle and nanoclusterfilled resin" 2) or "CAD/CAM (resin) composite" 3,4) , contains nanoceramic particles (silica-and zirconia filler/cluster filler) bound in a resin matrix 1) . The other resin-ceramic CAD/CAM material is VITA ENAMIC (VITA Zahnfabrik), a so-called "hybrid dental ceramic" containing a feldspathic-based ceramic network and a reinforcing polymer network 5) , previously also named "resin infused ceramic hybrid" 2) or "polymer-infiltratedfeldspathic ceramic-network material" 4) . Disregarding the varying nomenclature due to the different composition of the two materials, both manufacturers claim their material to have numerous advantages such as high flexural strength, lower brittleness than silicate ceramics, or optimized wear resistance.…”

Evaluation of Bleaching on a CAD/CAM Hybrid Ceramic Material

“…A great variety of dental ceramics and a large selection of composite resin materials can be found on the market. Among the advantages of ceramics are a high flexural strength and great color stability, while disadvantages are high antagonistic tooth wear and high incidence of failure due to its brittle nature [4,5]. These two parameters are much improved in the case of composite resins, but the wear of the material itself is higher.…”

“…Manufacturers have been developing new materials for CAD/CAM systems in order to combine the advantages of ceramic materials (durability, color stability) with the ones of composites (improved flexural strength and low abrasiveness) [5,8]. Recent materials like Vita Enamic (Vita, Bad Sackingen, Germany) represent such great improvements.…”

Effect of Food Simulating Liquids and Thermo-cycling on flexural strength and surface hardness of a Resin Nano-Ceramic CAD/CAM Material

“…The flexural strength of the Lava Ultimate was examined after restoring the samples for 24 hours in dry air without any storage protocol and found that the composite resin materials showed higher flexural strength combined with relativity low flexural modulus and stated that this combination translates to an increased ability to withstand loading by undergoing more elastic deformation before failure (12) . Therefore, this study aims at evaluating the effect of food simulating liquids and thermocycling on the mini flexural strength and surface micro-hardness of a resin nano-ceramic CAD/CAM material.…”
